The calf in your avatar calls to mind the vagaries of recombining color patterns. A very conservative makred Polled Hereford cow (very little white) bred to a Red Angus bull gave us a goggle eyed red baldy cow with only a hint of white on her belly. That cow bred to a Red Angus has never had a calf with a single white hair. We bred her to a Polled Hereford bull, also pretty conservatively marked and got a calf that has red sides and back and the rest is white. She has more white then her granddam and sire combined.
When you throw color variations in it's alwasy a guess as to what you'll get. That same bull bred to solid cows throws calves with a little white on the belly and the tip of the tail and a broken white face.
